Forget about Half-Life 3, it appears Valve can count to 3 to this zombie game instead.

2017 release? I am afraid in Valve Time, it's more later than that. Valve hasn't made the announcement for a release date, just only they are developing it for quite some time. By 2017 it'll be a decade since HL2 EP2 and Team Fortress 2 were released. There had been some suggestions that even virtual reality mode might be in L4D3.
Ever since then, the gameplay in some Call of Duty games with zombies are more interesting than Left 4 Dead since they are not in arcade mode. Maybe it's time for gamers to see something new coming out of Valve.
I wouldn't bet on Half-Life 3 until Call of Duty 20.
